new emoji modal :horny:

Good morning sirs,

New emoji modal implementation just dropped like 10 hours ago, I am sure some burgers noticed. What changed?

  • now you can select options to make the emoji larger, mirrored or patted directly in the modal

  • better search performance: logarithmic time complexity in exchange of linear space complexity in the numbers of tags per emoji

  • better render performance, every time you make a search or change tab it won't re-generate the whole DOM from scratch; although there's still room for improvement

  • if you hover over an emoji you'll get some infos

  • emoji modal is well behaved, it won't try to overwrite a selection without your consent

  • emoji modal will let you know when your search query results in an empty set 💅

  • backend: now it is possible to add tags to non-marsey emojis

I hope this clears things up

I'm actually neurodivergent enough to want to know the details for this.

Don't mind emoji miss-typed emoij here and there :gigachad:

let mid = (low + high) >>> 1;

Ok now youre just showing off

I forgot than in JS you can do (low + high)//2 to use integer division and using floor() felt stupid

Anyone that uses bit shifts for division by multiples of 2 is based and redpilled tbh

fricking lol. Daily reminder that there's probably more algorithm design happening in that one js document than 99% of software devs will ever implement themselves (outside of school)

I don't JS on principal, is there a need in this case to unsigned right shift? Does js sometimes wrap around when bit shifting if both numbers are >= 0?

It's just a fancy division by 2 to get the mid index lol

In any event, I have a feeling that the true nerd approach would be to construct a radix tree. Should use less memory (I’m not sure about this part, js has interesting memory management) and be quite a bit faster, at least in theory. Not that it matters, this plenty good

I know, was wondering if it needed to be unsigned. Love your work
